Suprex® crucibles are carbon-bonded silicon carbide crucibles, which are characterised by excellent thermal conductivity and high chemical erosion resistance. Based on application and furnace type respective types of Suprex® are available.
Suprex® B: Recommended for copper and copper alloys in fuel fired furnaces.
Suprex® R: Recommended for aluminium/aluminium alloys melting and zinc oxide producing in fuel fired furnaces.
Suprex® E: Recommended for aluminium/aluminium alloys and zinc melting and holding in electric resistance furnaces.
Suprex® Typical Metal Casting Temperature
Suprex® B 800°C - 1400°C (1472°F - 2550°F).
Suprex® R 700°C - 1000°C (1292°F - 1830°F).
Suprex® E 450°C - 900°C (842°F - 1652°F).
Suprex® E - Plus 450°C - 900°C (842°F - 1652°F).
- Fast melting speed through high consistent thermal conductivity.
